My Short Summary:
Oregano, my favorite herb, "is well-known for its culinary and medicinal uses." ... "increasing the production of these classes of bioactive phytochemicals in oregano is a worthwhile goal to improve its nutritional and medicinal value."
Saleh et al. discuss the virtues of utilizing both symbiotic arbuscular mycorrhizal fungi (AMF) and atmospheric CO2 enrichment to improve plant growth and yield.
The authors write eCO2 and AMF application are "reliable techniques that can be used to improve growth and the nutritive and medicinal values of oregano, however their synchronous application is much more beneficial."
Figure 1:
Both photosynthesis and biomass were enhanced by eCO2 and AMF alone, and even more in combination. Compared to control conditions, photosynthesis increased by 22%, 32% and 87% and biomass increased by 58%, 69% and 114% in the AMF, eCO2 and AMF + eCO2 treatments.
